Microsoft's new Exchange 2007 server can be a Unified Messaging Server / Media Server, Live Communications Server (soon to be Office Communications Server) is an Instant Messaging / Presence and SIP proxy and both Nortel and Mitel are claiming to be the 'chosen' ones working with Microsoft.
Nortel outlines roadmap for Microsoft partnership
Microsoft Technology Centers Showcase Unified Communications with Mitel Solution
I think both vendors see the writing on the wall... With 60% of the enterprise mail server market, Exchange is a force to be reconed with. Let's face it, a large portion of that will upgrade to Exchange 2007 at some point. Why, if I have Exchange and have already purchased Exchange CALs and it will work as my VM server, should I go and spend big $ on a different UM solution and fight the integration battle.
MS Outlook owns an even higher percentage as the e-mail client of choice.
Microsoft is trying to position Office Communications Server (LCS follow-on) and the Office Communicator in the same mold. Office Communicator may become the softphone of choice as Outlook is the e-mail client of choice.
It is a pretty easy bet that MS will continue to own the desktop software market. The traditional phone vendor world has also done a terrible job with their desktop integrations. I don't think there will be a question as to whether MS can rule the desktop softphone market and thus drive their server software LCS sales.
I think the question will really be, how long will Microsoft need to keep those relationships around... if they are really even "real" relationships to begin with or just old school vendors trying to hang on to those licensing dollars.

Everything is free except the hardware on which to run your new system. That can be almost any old Pentium PC or a multi-processor RAID box with mainframe horsepower. We also want to get TrixBox properly configured to support our next free application: TrixBox MailCall.
It'll let you retrieve and play back your email messages using any touchtone telephone and your TrixBox 1.1 system. And, yes, you'll need TrixBox 1.1 to make everything work.

So why would you bother use them? For the quality of the deployment (QOD? :-). By logically segmenting the voice and data worlds disruptions in either world will not affect each other (hopefully). You can firewall or use access lists between VLANs to help secure your VoIP deployment. Also, if you want DHCP / DNS to work differently for the phone system it doesn’t affect the data network.
I’m not going to get into the intricacies of VLANs here. Here’s the wikipedia entry (http://en.wikipedia.org/wiki/Vlan) which will help a bit. Get a couple of switches that support VLANs and play with them a bit… learn how to trunk VLANs between switches and how to statically map ports into VLANs. Learn them, live them, love them… you’ll use them all of the time.
On most VoIP deployments I’ll use 3 VLANs at a minimum. Data, Phone and Management. Data is the default VLAN and used for all PC’s, servers & printers. Phone is for all phones, gateways & PBX equipment. Management is for switch / router management IP’s.
Here’s what the VLAN diagram would look like:
Statically map the PBX and gateway ports into the Phone VLAN. Setup all of the ports that will connect to PC’s and phones with the Data VLAN as the default VLAN (untagged) and the Phone VLAN as a tagged VLAN. That means that devices ‘tagging’ their traffic for the Phone VLAN will be placed in that VLAN and devices that don’t know how to tag their traffic will be in the Data VLAN.
Manually set your IP phones to be in the Phone VLAN. This means the phone will tag it’s traffic for that VLAN and pick up DHCP from that VLAN. It is possible for some phones to pick this up off of the initial DHCP reply to the phone and then switch to the Phone VLAN and get another DHCP address from that VLAN. However, now you are depending on the DHCP server on the Data VLAN to be working.

Cabling - Make sure your network cabling is up to standards. Properly run Cat 5/5e/6 cabling with patch panels in the closets & wall jacks on the wall. Use manufactured patch cords. And if you really want to be sure it is right, have it certified by a cabling contractor.
Network Switching - This is one of the harder pieces and critical to the success of your deployment. I won't pretend to be able to describe how to properly design a network in a few paragraphs because every organization is different. Here are some basics though.
- Think about the core of your network. If everything ties back to a single location things are pretty simple. Where are your servers, your wiring closets, your wide area connectivity & your outside world connectivity? Start at the core and work out from there with a simple star topology (don't try to connect closet to closet to closet, instead connect each closet to the core directly).
- What other critical line of business applications do you run that may need to be considered in the design.
- What do you have for existing equipment that you might be able to utilize?
- Figure out which manufacturer's gear you want to utilize and learn the different models and their options. This is important! Know your product!
- How are you going to power your hard phones? PoE switches, mid-spans (power injectors) or power bricks at each desk?
- How about power protection? Most UPS manufacturers have calculators on their web sites that allow you to estimate consumption and run times of their gear.
Here's an example of a physical network design with a core server room (the core closet area is sometimes referred to as the MDF and the remote closets as IDFs).
Above we see the two closets linked back to the core at 1 Gbps, one with fiber because of distance from the core, and the second with Cat 5e / 6 copper. The servers all connect in to the core network switch at 1 Gbps and the firewall and router connect in to the core. Simple, clean efficient.
I like the HP switching gear (it's about 60% of the cost of an equivalent Cisco design, lifetime replacement, support and software updates). They have a nice broad range of products, their QOS seems pretty good and they are easy to configure. Don't' get me wrong, I like the Cisco stuff too and design plenty of networks with it. I just think I get more bang for the buck with HP. If I need to cheap things out, Linksys has some inexpensive managed PoE switches and so does Dell, Netgear and DLink.
Try to stick with managed switches so that you can create VLANs. Most modern managed switches will support Quality of Service (QOS). Some of the really cheap PoE switches are unmanaged (Netgear, DLink have some models like that).
Adtran makes some nice little stackable PoE switches (1224 series) and they even have one with an integrated router module (1224 r). This makes for a nice all in one device at remote WAN connected locations.
Don't have the coin for all new fancy gear? First off, prepare yourself for small voice quality issues. If you can live with that (hey we all put up with cell phones right?), take the above network design principles into account. Good cabling, star topology, avoid linking switch to switch to switch. Oh, and forget about trying to use any old hubs you have... switches only.
Remember, cabling and switching are the foundation of your VoIP deployment. The rest of the house is only as good as the foundation. Take the time to get it right and people won't be reaching for your throat. Next article I'll get into VLAN design and maybe QOS... we'll see how long it runs...

Snap works by sending the phone number you wish to dial to your PBX and initiating a call back to your phone. Once your phone rings you pick it up and it will be connected to the number you dialed.
For Outlook users, the call pop-ups are tightly integrated.The flexibility comes from it's Multi-Connection technology. If you travel between work and home, or would like to have seperate settings for different situations then this feature will be extremely useful for you. You simply dial via a different connection by using the "arrow" to the right of the Dial button to access these connections.
The latest version of the product (0.7) adds TAPI (in the Pro version $29.95) and eyeBeam 1.5 integration.

Paragon reports that the phone has been tested in the United States with some 30 different SIP infrastructures and providers.
The phone also sports PDA functionality with e-mail, calendar, a web browser and a camera (1.3 M pixel).
The software in the phone is based on Linux. At its core, the phone utilizes an Intel PXA271 processor.
Battery life was worked on extensively with the phone. Apparently 70 to 100 hours of standby time can be had, even with both radios turned on.
Here are the impressive published specs... http://www.parawireless.com/dmen.htm
Paragon has recently opened an office in Dallas with two employees and has approximately 40 employees in China. http://www.parawireless.com

In what no doubt is the initial release in a new series of phones, Polycom has introduced the new SoundPoint IP 430. The 430 would be considered a replacement for the SoundPoint IP 300/301.
One of the pieces always missing in the 30X line (and the 50X) was true Power Over Ethernet (802.3af). A special cable had to be purchased with the phone in order to support PoE. This finally has been addressed in the 430.
The IP 430 is an enterprise grade piece of equipment designed for a typical cubicle worker. It has the solid feel that businesses demand and we have come to expect from Polycom. A robust set of features is available on the phone including:
- Full duplex speakerphone featuring Polycom Acoustic Clarity Technology
- Two 10/100 Ethernet Ports
- 2 Lines
- 3 Way Local Conference Calls
- Amplified headset RJ-9 jack
- SIP Protocol
- Call park
- Hold and transfer
- Shared call / bridged line appearance
- Multiple call appearances
- Instant Messaging
- Integration with Microsoft Live Communications Server 2005
- New secure provisioning capabilities

I've had one of these for a while and tried it successfully on sipX and Asterisk systems.
The Hitachi WIP 5000 WiFi phone is a nice quality set. It feels solid to the hand and not just like a cheap piece of plastic.
Wireless network setup is not for a noob but not overly difficult. Only open and WEP 64/128 are supported for modes. It would be nice if WPA was also available... most people get turned off when only WEP is supported.
The screen is a monochrome LCD with a backlite. Very easy to read and a reasonable size.
There is a cool optional USB cable available for charging the unit while on the road. There are also extra batteries & carrying case to go with the phone. Batteries are easy to change but a single battery should last most users a full day.
There's also headset jack on the left side of the unit allowing for hands-free operation.
As with any WiFi phone you'll want to watch the number of sets per access point but you should be pretty safe with 5 to 6. If your users aren't that active you can probably get away with more.

Version 1.1 of eyeBeam was a pretty solid product with good support for USB headsets... especially for the uber cool Plantronics CS-50 USB (can answer and hangup calls right from the wireless headset).
There were some minor annoyances however like when you double clicked on one of your contacts it would open up an instant message box instead of dialing the user. That is now a user selectable option in 1.5.5.
Speaking of contacts, the Calls and Contacts "wing" is now cleaned up a bit (call logs are on a separate tab rather than clogging up the Contacts page). Contacts can also now be importand from Outlook .pst files in addition to the .csv and vcard files.
There was also a bug in 1.1 now allowing for Consultative / Warm / Attended (I've seen it called all three) Transfer. This problem is now fixed in version 1.5.5.
The entire Options menu is now cleaned up. Device support seems simpler as does maintaining status messages for presence. Ringtones are now possible (.wav files only).
Another nice new feature is the ability to do Audio, Video & Signaling QOS usinging DSCP/TOS values. We usually setup HP gear in for QOS COS 6 (DSCP 48 is typically where COS6 maps in to by default) and Cisco gear for QOS COS 5 (DSCP 40, that's what Auto QOS does for Cisco phones so I usually just play along...).
One annoying change is that they swapped the buttons for pickup and handup. The green button is now on the left and the red 'hang-up' is now on the right... grrr....
All in all, I'd sait is's a worthwhile upgrade. If you're having issues with things like the Transfer function they'll probably even give you the upgrade for free.... nice folks that they are....

It has its own web site at: www.hudlite.org
The trick to making it work is that your devices should all be named SIPx where 'x' is the extension. Also, use your deskphone's extension and SIP password.
The default HUD Lite server password is 'password'. To change it see this post: http://www.hudlite.org/modules/newbb/viewtopic.php?topic_id=14&forum=1
HUD Pro is only available if you have a Fonality PBX. Apparently it only works with Asterisk 1.09 at the moment. It would be nice if they allowed you to purchase just HUD Pro but I guess they are counting it as one of their PBX's competitive advantages. It is a nice looking product and seems to work very well.

The install was very simple on to a system I've had running A@H 1.28 and sipX.
Once the CD installation was complete, logged in as root and ran netconfig to setup an IP address on the system.
From there I was able to hit the box from a web browser on another machine and work with freePBX as in version 1.28 of A@H. Love the new updating options with trixbox and freePBX. Hopefully it is the end of full re-installs. This was one of the big issues I had with the product before. That and the hangup with the Asterisk At Home name.
I like the looks of the new Hud Lite application on the pbx. Still fighting with trying to get it to function as a softphone (not sure if it even can yet). One thing I don't like is that the extensions you want to see in hud lite must be entered in separately from the extensions when setup in freePBX.
I'm also fighting with some call quality issues with Counterpath's eyebeam 1.1 with Asterisk. I had this issue with A@H 1.28 and they continue. The hard phones seem to work fine and eyebeam works fine with the sipX / Pingtel pbx I'm working on.

Adtran rep came into the office to give us a demo on the new 7000 series IP PBX. Seems to be a nice little unit. Support for only up to 50 users but a larger unit for 150 ppl is due out next year.
They are selling re-labeld Polycom phones and Counterpath eyeBeam (no video) for their softphone. They have an Adtran phone they are working on.
The system definately needs some software updates and should be up to speed by the November patch (early December).
The GUI is typical of the entire Adtran switch/router line. Looks pretty nice and easy to use.
See more about it here: http://www.adtran.com/adtranpx/Rooms/DisplayPages/LayoutInitial?Container=com.webridge.entity.Entity%5bOID%5b666DBE59D3CCEE4B9990879A34E02589
Global IP has modified xten Pro a little bit to create a soft phone that has a Tapi driver. They call it X_TAPI Pro. Check it out here: http://www.xten.de/(3n3te155nucgdr2f4tmrcd45)/_Pages/NoFrames/PageBuilder.aspx?content=1aa9a817971e445ea0fe822aa6cebce8
It seems to be able to pop contacts from the user's contacts folder only.
A more interesting product that can work with any Tapi driver is Identapop. Check it out here: http://www.identafone.com/cidpop.html
Identapop can pull contacts no only from your local contacts folder but also from public folders. It also has the ability to log calls to Outlooks Journal for historical call information.
SIP Tapi is an open source TAPI driver that seems to allow outbound dialing only. It can dial any contact in outlook. http://sourceforge.net/projects/siptapi/
Here's a wiki entry on how to setup SIP Tapi with sipxpbx: http://sipx-wiki.calivia.com/index.php/Click-to-Dial_for_Outlook%2C_CardScan%2C_ACT%21_using_SIP_TAPI
Asterisk at Home has changed its name!
The A@H project (formerly at http://asteriskathome.sourceforge.net) is now called trixbox. The new web site is www.trixbox.org.
For those not familliar, this project encompases CentOS Linux, Asterisk, FreePBX (formerly Asterisk Management Portal [AMP]) and a few other pieces of open source software.
